1. Lo lus nug: Dab tsi yog qhov txawv ntawm Inconel 600, 625, 690, thiab ASTM A335 P2 / P5 / P9 / P11 steel kav?
Teb: Inconel 600, 625, thiab 690 yog npib tsib xee-raws li alloys nrog corrosion kuj zoo heev thiab siab - kub lub zog, zoo tagnrho rau tshuaj, petrochemical, thiab siab - kub daim ntawv thov. ASTM A335 P2, P5, P9, thiab P11 yog cov kav hlau hlau uas tsim los rau siab - kev pabcuam kub hauv boilers, fais fab nroj tsuag, thiab cov khoom siv hluav taws xob, muab kev nkag siab zoo thiab lub zog txhua yam. Qhov kev xaiv nyob ntawm qhov kub thiab txias, ib puag ncig corrosion, thiab txhua yam yuav tsum tau ua.
2. Nqe Lus Nug: Cov qauv thiab cov lus qhia dab tsi ua rau koj cov kav dej seamless thiab cov kav dej ua tau raws li?
Teb: Peb cov kav dej seamless thiab cov kav dej ua tau raws li cov qauv thoob ntiaj teb xws li ASTM A335 rau cov yeeb nkab steel hlau thiab ASTM B163 / B829 rau nickel alloys. Qhov ntev, phab ntsa tuab, thiab cov khoom siv kho tshuab tau nruj me ntsis raws li tus qauv tsim nyog kom ntseeg tau tias muaj kev ntseeg siab hauv siab - siab thiab siab - daim ntawv thov kub.
3. Lo lus nug: Dab tsi yog qhov loj me thiab phab ntsa thicknesses muaj rau cov raj thiab cov kav dej?
Teb: Peb tsim cov raj thiab cov kav dej hauv ntau txoj kab uas hla, feem ntau yog los ntawm 10mm txog 200mm OD, nrog cov phab ntsa tuab ntawm 1mm txog 25mm, nyob ntawm cov khoom siv qib thiab cov neeg siv khoom xav tau. Qhov ntau thiab tsawg kuj tuaj yeem tsim tau raws li kev thov.
4. Lo lus nug: Puas yog cov raj thiab cov kav dej no haum rau qhov siab - kub thiab corrosive ib puag ncig?
Teb: Yog. Nickel alloys (Inconel 600, 625, 690) muab kev tiv thaiv corrosion zoo heev thiab tuav lub zog txhua yam ntawm qhov kub siab txog 1000 degree. ASTM A335 alloy steel kav (P2, P5, P9, P11) yog tsim los rau siab - qhov kub thiab txias kev pab cuam thiab tuaj yeem tiv taus thermal stress thiab nkag mus rau lub sijhawm ua haujlwm ntev.
5. Nqe Lus Nug: Dab tsi ntawm qhov chaw tiav thiab kev sim kev xaiv muaj rau cov khoom no?
Teb: Cov raj thiab cov kav dej tuaj yeem muab tau raws li - dov, ci annealed, pickled thiab passivated, los yog polished tiav. Peb muab tag nrho cov kev ntsuam xyuas zoo nrog rau kev sim hydrostatic, NDT (ultrasonic, eddy tam sim no, magnetic particle), tshuaj ntsuam xyuas, kev kuaj tshuab, thiab ntawv pov thawj raws li ASTM cov qauv kom tau raws li cov neeg siv khoom tshwj xeeb.
